.To @ZZ whom, t 11i/ty concern:

Be it known that I, ADONIRAM J. COLLAR, a citizen of the United States, residing at Yreka, in the county of Siskiyou and State of California, have invented new and useful Improvements in Water-Gates, of which the following is a specification.

My invention relates to improvements in devices for controlling the iiow of water in pipes.

It consists in the combination of devices and in details of construction which will be more fully explained by reference to the accomp anying drawings, in which- Figure 1 is a sectional view through the inlet and outlet ports of my device. Fig. 2 is a sectional view taken on line of Fig. 1. Figs. 3 and 4 are side views ofthe body or carrier of the gate detached, showing the springpressed valves 20. Fig. 5 is a detail of a roller of modified form.

As shown in the drawings, A is a casing of any suitable or desired shape adapted to contain the gate mechanism. This casing has an inlet-opening2 at one side and a dischargeopening, as at 3, at the o posite side, these openings being substantia ly in line and provided with any suitable means connecting them with a conducting-pipe. The sides in which these openings are made and which form the seats for the closing-disks are inclined, as shown. The gate comprises a body or block 4, having a vertical tubular stem 5 extending upwardly through the top of the casing, with which it may form a tight oint, and having the interior of the upper end reduced and threaded to form a nut, into which a correspondingly-threaded stem 6 enters and is turnable. This stem extends up through the cross-bar of a yoke, as at 7,

which serves to guide the stem and which is chambered to receive a collar fixed upon the stem, as at 8so that the stem will be turned without advancing, and the screw-threaded portion turning in the nut ofthe tubular part 5 will raise or depress the part 5 and the b ook with which it is connected. This block has two faces, one of which corresponds with the inlet-opening 2 and the other with the outletopening 3 of the case A.

Upon the side of the body or carrier 4 which is adjacent to the inlet-opening is a disk 9, closable against the seat in the interior of the case and against the inlet-opening. This disk has an inwardly-extending slidable portion 10, which lits and-is vertically mov-l able in a corresponding channel, as at 11, formed in a contiguous end of the carrier 4; This portion of the carrier has a horizontal transverse channel 14 made through it and adapted to contain a roller, as at 12. The disk 9 has an inwardly-projecting lug or shank 13, which is vertically slotted to receive the roller 12. The roller extends through the opening at 13a and lies within the channel 14, which is formed in this side of the block or carrier 4, andthe operation will then be as follows: When the ate is closed and the disk .9 pressed against t e seat of the inlet-opening, that part of the slot or channel 13a which is coincident with the vertical side of the slide 1() presses against the roller, and the opposite side of the roller in turn presses against the back of the channel 14, the position of the roller being then substantially near the top of the slot or channel 14 and near the bottom of the `slot or channel at 13a. Then this being the condition, when the carrier or block 4 1s raised the roller will revolve upon these two opposite contacts, and by reason of the inclination of this side of the carrier-block the disk 9 will be released from its contact with the seat and exert no pressure which would prevent the gate from being lifted when the roller has reached the end of its travel. Upon the opposite side of the carrier-block 4 is itted a disk 15, similar to the one shown at 9 and having a shank 16 extending into a vertical channel in this side of the carrier-block, the shank being vertically slotted, as shown.

17 represents a slot or channel made transverselyin the carrier-block 4, and within it is a roller 18, similar to the roller 12, previously described and operating in substantially the same manner to rovide an antifrictional bearing, so that when the carrier-block 4 is raised this disk will be released from its pressure upon the discharge-opening seat. As there is a certain amount of water which may leak in around the inlet-controlling disk 9, and thus produce a pressure inside of the carrier-block and against the lower disk 15, I have shown a means for relieving this pressure, which consists of slots 19, made through the face of the disk 15 and communicating directly with the interior of the carrierblock.

20 represents small spring-pressed valves, which coincide with the openings 19 of the disk 15, and when the carrier-block 4 has been pushed down so that by reason of its TOO IIO

divergence and by the movement of the rollers 12 and 18 the two disks 9 and 15 have been forcibly closed against their respective seats, the movement of the carrier-block wedging them outwardly, as shown, the valves 20 will be moved in unison with the carrier-block and will close over the openings 19, thus preventing any escape of liquid through these openings.

As soon as the carrier-block is raised, as previously described, it will by reason of the rolling friction of the blocks move freely between the disks 9 and 1 5, the latter remaining in line with the seats against which they close until the rollers reach the bottom of their travel, and as the valves 2() are carried with the block 4 it will be seen that they will be raised, so as to expose the openings 19, thus allowing the escape of any water under pressure which may be contained and which will ress against the disk 15, thus instantly reieving this disk from pressure and allowing it to be carried `upwardly with the block 4, and thus open the passage through the gate. The incline upon this side of the case is greater than that upon the inlet side, and thus insures the more rapid opening of the discharge valve or disk. In order to still further relieve the moving parts from pressure, I have shown channels, as at 21, made in the sides of the gate-chamber, which are at right angles with the sides through which the water passes, and through the carrier-block 4 is a corresponding channel or opening within which fits a roller 22, the ends of which project into the channels 21, and thus provide a rolling friction as the carrier-block is raised or depressed, which makes it easy to be moved under any conditions. The ends and intermediate portion of the roller and its corresponding contacts in the channels and in the block 4 may be toothed or corrugated, as shown in Fig. 5, to insure the rolling friction.

In the bottom of the casing or chamber A is fitted a plate or bar 23, the ends of which .incline downwardly from the center toward each of the openings 2 and 3, and this plate or bar is in such position that when the block 4 is depressed to Close the passage the lower edges of the disks 9 and 15 will first rest upon these inclined surfaces, thus arresting the disks in the proper position to be subsequently closed against the seats when the block 4 is further depressed and by its wedge form acts to force the disks to close the openings. The rollers 12, 18, and 22, acting as previously described, allow the block to move with the least possible friction, and the gates 2O being moved with the block close the openings 19 in the disk 15, thus entirely closing the gate. The ends of the roller 22 will be arrested by the end walls of the guidechannels when the block is lowered to fully close the gates, while the rollers 12 and 18 similarly contact with the upper ends of the slotsin which they trvael. All these rollers are removable endwise from the containing slots when the block has been lifted out of the casing. The by pass valves 20 are loosely carried upon guide-pins which allow the valves to tilt freely, and thus seat themselves fairly over the by-pass openings, and as the incline of the discharge-seat is greater than the incline of the inlet-seat it will be seen that the discharge valve or disk will be the first released from pressure, so that the gate is very readily opened.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
